CLOTH PERFORATING OR MARKING MACHINE.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed December 23, 1918. Serial No. 268,041.

To all whom it may concern:

Be it known that we, NICOLAS KoMow and GEORGE M. HOSKWITH, citizens of the United States, and both residents of Brooklyn, in the county of Kings and city and State of New York, have invented a new and useful Cloth Perforating or Marking Machine, of which the following is a specification;

The invention is an improvement 1n machines for perforating or drilling multiple plies of fabric, such as are used for marking, the corners of pockets or for makin ventilation holes in piled layers of cloth for garments, or for similar purposes. The object is to provide a machine, simple in construction and convenient to use, wherein the rotary and depressible needle is effectively guided and laterally supported, so as not to bend when forced downward into the pile against the resistance'which the superposed layers offer to its passage. The preferred embodiment of the machine comprises an electric motor and a hollow drive shaft and guide tube, which are fixed, as regards vert1- cal movement, upon a suitable portable stand, and a needle shaft and needle which are splined in the tubular shaft, so as to be movable vertically therein while partaking of its rotary motion. A handle on the upper end of the needle shaft enables it to be depressed, and it is preferably automatically raised by springs encircling lateral glllClGS, which prevent twisting of the upper part of the vertically movable structure. The tubular needle guide extends downward into proximity to the base, so that the use of a long projecting needle without adequate lateral support is avoided. In the best and simplest embodiment of the invent1on the armature shaft and guide tube are combined in one part.

In the accompanying drawings:

Figure 1 is a side elevation of the machine with a part thereof in vertical section, the machine being shown resting upon a pile of cloth with the vertically movable parts in the normal, raised position, broken lines being used to represent the depressed position; and

Fig. 2 is a view looking at right angles to Fig. 1, partly in vertical section and partly in elevation.

An incased electric motor 1 is mounted in laterally projecting relation upon the upper portion of a standard 2, which rises from an appropriate base 3 adapted to rest upon the cloth. A horizontal handle 4 projecting from the motor casing enables the machine to be readily moved about. I

The armature 5 of the motor is disposed with its axis of rotation vertical, its shaft 6 being journaled in bearings in the top and bottom of the casing. The said shaft is hollow to form a guide, which is extended at 7 for a substantial distance below the casing. Preferably a guide tip 8 is screwed removably upon the lower end of said tubular extension, this tip having a reduced opening forming a slide bearing for the needle 9 adacent the plane of the base. The bore of the rema nder of the tubular shaft 6 may be somewhat larger, as shown, without permitting the needle to bend to any substantial degree.

The needle is coupled at 10 to the lower end of a needle shaft or rod 11, which has slidable bearing in the tubular shaft 6. A

screw or key 12 projecting inwardly of the depressing handle 15, which is held by lateral guides against rotation about the vertical axis. The said guides preferably comprise two rods 16 projecting downward from the handle in spaced relation at opposite sides of the needle rod, into guide tubes 17 inserted in the motor casing. Helical springs '18 coiled about the guide rods, be tweentubular abutments 19 at the lower ends of the guide tubes and shoulders 20 at the upper portions of the rods, serve to raise the handle, needle rod and needle, when downward pressure is removed from the handle. In this particular construction the rods 16 do not fit closely in the tubes 17 the springs 18 serving as supplementary guides be understood, is recessed at 22, Where the needle passes. The operator then removes of the slot 13 abutting against the screw 12, l

or by any other suitable stop which may be provided. V

What we claim as new is: 7

1. A portable cloth perforating machine comprising a support, a motor fixed thereon and having a vertical hollow armature shaft provided with a downward guide extension extending into proximity to the base, and a vertically movable part having a handle and including a needlerod slidably keyed in said shaft and a needle guided in said extension.

2. A portable cloth perforating machine comprising a support,'a motor casing and motor fixed thereon and having a vertical hollow armature shaft, a guide tube extension projecting downward from the motor, and a vertically movable part having a depressing handle andincluding a needle rod and needle operative through the armature shaft and guide extension and keyed to said shaft.

3. A portable cloth perforating machine comprising a support, a motor fixed thereon and having a vertical hollow armature shaft provided with a downward extension extending into proximity to the base, a verti cally movable needle rod splined in said shaft, a needle coupled to the needle rod, and a guide tip on the extension affording a sliding bearing for the needle.

4:. A portable cloth perforating machine comprising a support, a motorofixed thereon and having a vertical hollow armature shaft, and a vertically movable part comprising a needle rod andneedle operative through the armature shaft and splined thereto, a handle connected to the upper end of the needle rod, and side guide rods projecting downward from the handle and 00- operating with sockets in the support.

5. A portable cloth perforating machine comprising a support, a motor fixed thereon and having a vertical hollow armatureshaft, and a vertically movable part comprising a needle rod and needle operative through the armature shaft and splined thereto, a handle connected to the upper end of the needle rod, side guide rods projecting downward from the handle and cooperating with sockets in the support, and elevating springs encircling said side guide rods.
